Boater Safety Rules for the Bridge Project Site

You know boating near the project site is restricted and dangerous, right? Not watch-out-for-sharks dangerous yet close to it. (Pity the kayaker above!)

From the New NY Bridge website:

• Stay clear of all overhead work and maintain a safe distance of 1,000 feet from all construction equipment and support vessels.

• Use the center 600 feet of the Main Channel (when available) to navigate in a north-south direction with no wake at a maximum speed of five knots.

• All bridge piers and abutments are protected by a 25-yard security zone.

• No unauthorized vessels are allowed in the Safety Zone surrounding 16 construction barge mooring locations. Lighted buoys mark the zone and mooring locations.

• Regulated Navigation Areas (RNAs) stretch 500 yards north and 500 yards south of the existing bridge. No vessel may stop, moor, anchor or loiter within the RNAs.

• The Eastern RNA will be extremely active and vessels transitioning to and from the eastern shoreline at Tarrytown should approach and depart to the north. The Western RNA will be impassable at times and mariners should stay clear of the area.

• Lighted channel markers provide recreational boater access to the Piermont waterfront.

• Construction barges and other vessels on the site are being tracked by GPS technology.

• TZC will monitor Marine Radio Channel 16 to communicate with boaters.

The New York State Thruway Authority provides this information as a public service. Any reliance you place on such information is therefore strictly at your own risk. Nothing in these guidelines shall supersede the actual construction conditions, and regulations set forth by the U.S. Coast Guard.

Watch out for fins in the water! I’d like to know what you think.

TBT: Looking Back at Earlier Project Photos

What are those things floating in the river? Debris? No, those are piles, and the story that day (June 2014 media tour) was pile cleansing: scooping out the muck prior to filling them with concrete and rebar (reinforced steel).

Did you notice the super crane is on the south side of the bridge? It had recently arrived at the project site, where crews waited for low tide a few days later before limbo-ing it under the current bridge.

Oh my, how tiny it looks at ground level. This is from early September 2015, when crews began building those now-419-foot tall towers using self-climbing jump forms. Are those cartoon heads in the red truck?

Here’s a memory from days gone by, when tolls were 50 cents each way. One-way collection was adopted August 12, 1970, and toll booths on the northbound lanes were removed.

And guess what? We made it through the Ides of March. Ha!

I’d like to know what you think.

Connecting Rockland Approach, a fifth Gantry and ongoing Main Span Channel Closures

Since media were invited onto the new westbound span, crews connected the Westchester approach and the main span, the Rockland approach and the main span are being connected, and there will soon be a fifth overhead gantry. Did we miss the fourth?

Tha main span navigation channel continues to be closed periodically until next December. While boaters may be pleased to hear this, I’d like to enjoy the spring, summer and fall before winter comes around again.

Aftermath of That Morning in December 2014

View from the EarthCam® construction camera in Tarrytown December 16 at 9:15 a.m.

Sometimes you follow your gut, and the resistance you encounter tells you you’re onto something, so you push harder. I FOILed the Thruway Authority shortly after the batch plant accident more than two years ago and was consistently stalled.

View from the EarthCam® construction camera in Tarrytown December 16 at 9:30 a.m.

What the agency gave me was five internal emails from TZC stating an incident happened, and no one was hurt. Thankfully. My FOIL request ended with a project official calling me “to tidy things up,” after which the Thruway Authority’s legal department told me it considered the matter closed.

Really? Here’s what I recently found that confirmed I was on the right track.

Concrete Silo Collapse By Jenna Ebersole

Law360, Washington (January 7, 2016, 8:19 PM EST) — The contractor replacing the Tappan Zee Bridge in New York sued two companies based in Wisconsin and Switzerland Thursday in New York federal court, accusing them of shoddy work that led to the collapse of silos on a concrete plant mounted to a marine barge in the Hudson River in 2014.

Tappan Zee Constructors LLC said Maxon Industries Inc. and X-Tec Swiss AG designed and constructed defective silos, seeking at least $25.7 million for higher costs as a result, including labor, equipment and other construction costs. The group said that the silos on one barge that collapsed in December 2014 were defective and that the constructors discovered similar defects with the second plant.

“Defendants’ acts or omissions to act, including their deficient and inadequate structural design of the silos in accordance with the applicable silo-design code service loads, and their failure to construct hopper and vertical wall steel plating thickness in accordance with X-Tec’s own fabrication shop drawings, caused the collapse,” the group said.

The constructors said they signed an agreement in May 2013 with Maxon for two batch plants, including the silos, after coming to an agreement on two new bridge structures over the Hudson between Rockland County and Westchester County. Maxon then entered an agreement with X-Tec for certain designs, the group said.

“Maxon and X-Tec knew that the batch plants were to be mounted on marine barges and used on the Hudson River,” Tappan Zee Constructors said.

Maxon was [nearly one year] late on a promised Aug. 1, 2013, supplying of the plants, the constructors said, but they were used as intended until the collapse of one silo [December 2014], which pulled down two adjacent silos. The group then discovered defects with both plants, the constructors said.

The complaint said the constructors group “was compelled to stop using the batch plants and required to materially alter its concrete operations until it determined and effectuated appropriate modifications and repairs to the batch plants and obtained a third batch plant to supplement its operations.”

The group alleges breach of contract, negligence and malpractice, among other claims.

“Defendants acted negligently and breached their duty of care by, among other things, providing an inadequate structural design of the silos under applicable silo-design code service loads,” the constructors said.

Representatives for the parties could not immediately be reached for comment late Thursday.

The constructors group includes Fluor Enterprises Inc., American Bridge Company, Granite Construction Northeast Inc.and Traylor Bros. Inc. in a joint venture, according to its website.

Tappan Zee Constructors is represented by Paul Monte of Peckar & Abramson PC.

Counsel information for Maxon Industries and X-Tec Swiss was not immediately available Thursday.

The case is Tappan Zee Constructors LLC v. Maxon Industries Inc. and X-Tec Swiss AG, case number 1:16-cv-00126, in the U.S. District Court for the Southern District of New York.

TBT: Two Years Before the Towers’ Completion

This little guy is smiling because he completed the Tower Crane Challenge at the Outreach Centers. I’m smiling because my hunch about something was correct: while I surmised the Thruway Authority wanted to dissuade me from learning what happened two Decembers earlier, another reporter did.
